To allwhom it may concern: I

Be it; known that 1, WILLIAM A. Dan- ,IELSEN, a citizen of the United States, residing at Palatine, in the 'county of Cook and State of Illinois, have invented certain'ncw and useful Improvements in -FlushTank.

"Valves, of which the following is a specification. H I

My invention relates to'flush tank valves, and the object thereof is to furnish a simple.

I eiiective and durable device of that description. The valves of this kind in general use are provided withhinged o1" pivotediparts, which are subject to'wear' and'not easily replaced. In applying the' principles of -my invention I .do away'with wearing-1 anism, which cannot break, wear out for get out of order, and I moreoverprov de a seatin which the olas tic portion can be readily replaced Iwithout thQXQl'ClSB "of mechanical skill, with simple toolsand at. pine-- tically no expense.

'lheapririciples of my inve" trated in the drawiugs in wh ch-Q 'Fign're 1 is-a top ;vievv tliereo f.', I Fig. 2 is a side elevation partiallyfin section.

Fig. 3 shows a modificationdofthe:device.I

Further describing'iny invention with reference to the drawings: .1 isthe bottom, and

2 the sides of a flush ta'nk. ing 3 of my improved valve-is preferably integrally formed, and the threaded portion 85 4 is. extended downwardly through the tank bottom. A gasket 5 is interposed between the shoulder (i'and the bottom 3 of the tank.

' and the whole is secured in place by the nut 7 to form a fluid tight joint. The upper 40 part of the casing is broadened to form an annular flange 8, and has an off-set elbow 9, to which is attached the overflow pipe 10. An annular groove 11, is connected with said elbow and provides means by which overflow from the tank through pipe 10 may be conducted to the waste pipe without its movement being interfered with by the valve headf A n annular gasket 12 is placed on 'the flange 5 and held securely in place by the ring T which may be clamped thereon by screws 14. The inner edges 15 of said gasket are turned downwardly to for-man annular scatter the valve head 16. The latter should he buoyant, and to -this end maybe a sealed body of hollow metal. al-v Fresh-TANK VALVE.

When in its seat or closely approximated thereto, the absence of water underneath to 'seal the mouth causes the valve head to close with its whole weight, thereby sealing itself more readily and effectively. 1

A modification of my device is shown in Fig. 3, in which the'iiange 8 isinternallv threaded to take the peripherally threaded ring 13. If desired a plurality of supports 25 may be attached to said ring and ex-" tended upwardthereon and closed at the top to form a cage which will act as'a guide for 1 the valve stem and head.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent 1 v f 1. A flush tank valve'comprising an out let casing havin a seat provided with an ,7 upw'ardly extended annular flange and an internally threaded rim on said flange, an elastic annular member seated on said flange and. having-a depending flap. a pe-" ripherally thrcaded ring for securing said elastic member within the said rim, a closure consisting of a hollow head in the form of an inverted truncated cone pro vided with an. air opening on the-underside thereof, and a cage attached to said ring and adapted to guide said closure with reference to said seat.

2. A flush tank let easing having a substantially cylindrical bore and provided v; an annular flange on the upper end thereof, an elastic annular member seated on said flange and having a depending annular. flap lying against the Wall of Said hero, leans for attaching the elastic member to tl lange and a float valve in the form of a hollow inverted frustum of ateo cone having a elesed oase'and v. t within said casing and the liar;

3. A iiueh tank va a comprising an outlet casing hat inn" a eunstantially cylindrical. bore and 3' l vith an annular end flange an el r member secured on said flange a depending annular edgeconro to the wall of the bore to form a valve neat and a hollow closure head in tlie term or a iirustum of an elongated inverted cone having a closed base and adapted to seat within the casing and the degendii a; the elastic member.

- e. A flush tanl: valve comprising a elosure consisting of a hollow head in the form t of a frustuin ii an elongated inverted cone having a closed base and open at its, small end, an outlet casing havirw a bore whose wall is substantinll" wlindrmal, and an annular elastic ,7, ;'-1eeurcd upon the upper end of said ens till having its inner edge turned don-nu v y against the wall of the bore oi the easi the tapered wall. of

valve comprising an out-- said head being adapted to engage within the downturned edge of the gasket when the valve is closed.

5. A flush valve comprising a chambered casing through which water is adapted to flow, a cylindrical rubber valve seat having an annular flange, means for clamping the flange tightly against the valve casing, and a hollow valve adapted to enter the seat and engage the cylindrical portion thereof.

6. A iiush valve comprising a chambered casing through which water is adapted to flow and having an internally threaded flange at its top, a ring screwing into the flange, a rubber valve seat of annular form of less diameter than the ring and having an annular flange clamped between the ring and valve casing, and a rigid hollowvalve cngagcable internally oi the seat.

7 Ar flush valve comprising a chambered easing; through which water adapted to flow and having 'an internally threaded flange at its top, a ring screwing into the flange, a rubber valve seat of annular form of less diameter than the ring and'having an annular flange clamped between the ring and valve casing, and a rigid hollow valve engageable internally of the seat, said ring having a cage extending upwardly therefrom for guiding the hollow valve and torming a handle for the screwing and unscrewing of the ring.

In witness whereof, I have hereunto subecriberl my name this 11th day or December, 1915, in the presence of two subscribing witnesses.
